Vladimir Putin said he will work with 'whichever president is elected by the American people'

Vladimir Putin has said Russia can work with Mitt Romney if he is elected US president - even though the Republican candidate has called Russia the United States's "number one geopolitical foe".

In an interview broadcast by the Kremlin-funded Russia Today TV channel, the Russian president said: "We'll work with whichever president is elected by the American people. But our effort will be only as efficient as our partners will want it to be."
